Description
The PLSES belongs to the IMfinity platform, which covers motors from 0.09 to 1500 kW in classes IE3 and IE4, and the PLSES 4500 stands next to the standard series in the catalogue. The motor has 2, 4 or 6 poles and a steel shaft. The open drip-proof IP23 version with self-ventilation gives more power in a smaller frame than closed IP55 motors, so such machines are installed in clean rooms. For adjustable-speed drives the motors are supplied with, among other things, braking resistors. The series covers the range of large motors in 0.4 kV networks (up to 1 000 V), and for drives up to 900 kW there is no need to move to high-voltage machines. Motors for 6–10 kV are not in the range.
How to choose
If the drive power is up to 55 kW, closed LS or LSES with IP55 protection are sufficient. From 55 to 900 kW the PLSES is used when the motor is in a clean dry room, because IP23 does not protect from dust and splashes. The number of poles 2, 4 or 6 determines the speed, and the shaft height of 225–400 mm grows with power.

FAQ
What is the power of PLSES motors?
55–900 kW with shaft height 225–400 mm, 2, 4 or 6 poles, voltage 230/690 V, frequency 50 and 60 Hz.
What does protection rating IP23 mean for these motors?
It is an open drip-proof version with self-ventilation. It requires clean rooms, for example machine halls and pumping stations.
Is there a PLSES version for 6–10 kV?
No, high-voltage motors of 6–10 kV are not in the range. The PLSES works up to 1 000 V.
Why is IP23 more advantageous than IP55 at high power?
An open self-ventilated motor of the same power has a smaller frame than a closed IP55 one.
